I'm beginning to wonder if my tape device or tape is going bad. AFter a backup run tar exists with error tar tvzf /dev/nsa0 > t2 tar (child): read error on /dev/nsa0 : Input/output error gzip: stdin: decompression OK, trailing garbage ignored tar: Unexpected EOF on archive file checking status of the tape gives me mt status Mode Density Blocksize bpi Compression Current: 0x26:DDS-4 512 bytes 97000 disabled ---------available modes--------- 0: 0x26:DDS-4 512 bytes 97000 DCLZ 1: 0x26:DDS-4 512 bytes 97000 DCLZ 2: 0x26:DDS-4 512 bytes 97000 DCLZ 3: 0x26:DDS-4 512 bytes 97000 DCLZ --------------------------------- Current Driver State: at rest. --------------------------------- File Number: 1 Record Number: 0 Residual Count 8704 Now does ANY residual count indicate error? mt errstat gives me: mt errstat Last I/O Residual: 0 Last I/O Command: 08 01 00 00 14 00 00 00 00 00 00 00 00 00 00 00 Last I/O Sense: F0 00 80 00 00 00 11 14 00 00 00 00 00 01 00 00 00 00 00 00 00 00 00 F6 1F 40 08 00 6F 63 00 00 Last Control Residual: 0 Last Control Command: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Last Control Sense: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 okay. what does it mean? Residual count is 8704. yet, i/o residual and control residual is 0. my understanding of this is getting worse. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"
